Abstract
Inflatable straddle packers were used to isolate and test selected intervals in hole UAe-3. Packer seats were poor in the uncased part of the hole because of unstable wall conditions, and leakage around packers occurred during some tests. However, leakage generally was slight, as shown on pressure-gage charts, and had little effect on the tests. The static water levels in the intervals tested ranged from 31.6 meters (104 feet) below land surface in the upper interval tested to about 115 meters (377 feet) below land surface in the lower interval tested, indicating decreasing head with depth. The relative specific capacities of isolated zones ranged from less than 0.001 cubic meter per day per meter (less than 0.001 gallon per minute per foot) of drawdown to 0.898 cubic meter per day per meter (0.050 gallon per minute per foot) of drawdown.
